| Abstract | In order to decrease air pollution and save conventional energy, geothermal energy as a heat source for district heating system have been used widely in China due to its cleanness and lower operating cost. This paper describe the geothermal resource and district heating system in Tianjin. Heat load for one sample building was calculated using Icelandic heat loss calculation and Chinese building code. Based on it, both geothermal heating and fuel fired system using steady state model and dynamic model were simulated and results were analyzed. In addition, district heating system network was set up, pressure and temperature drop of pipelinewere calculated, the simulation results is satisfying. Therefore, dynamic simulation model is a powerful tools for designer to study the system performance and optimize the heating system. |
